(Finals Project) Formulas Using 2 Points

Distance Formula

• √((x₂ – x₁)² + (y₂ – y₁)²)

• (y₂ - y₁)/(x₂ - x₁)

• ((x₁ + x₂ )/2 , (y₁ + y₂ )/2)

The midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segments and of the endpoints. It bisects the segment.

• True

• False

Midpoint Formula

• (y₂ - y₁)/(x₂ - x₁)

• ((x₁ + x₂ )/2 , (y₁ + y₂ )/2)

• √((x₂ – x₁)² + (y₂ – y₁)²)

• ((x₂ + x₂ )/2 , (y₁ + y₁ )/2)

Slope Formula

• ((x₁ + x₂ )/2 , (y₁ + y₂ )/2)
